    Hi Daniel Ludwig, what did you take the power cord out off ? was it the computer or the monitor ? Have you tried doing it for the monitor and check the video cable is connected ok

    When you turned the computer do you hear beeping sound ? or the numlock of the keyboard light is working. IF the numlock light is working it's mean that your computer is working maybe your monitor connection or monitor itself. Can you trace the power cable and the VGA or video cable connection from monitor to the back of the CPU is connected properly

    a 2008 PC dead. well; the coin cell cmos battery is dead and so is the HDD.
    8 years old.
    we check the battery first called coin cell.
    below 2.9vdc is bad. coin, it is a $1 part.
    blinks power means error.
    means stuck in sleep or power failures
    no history told
    bought a dead 2008 PC? ?
    or run for 8 years and failed today
    or remove from storage after 3 years and is dead. the coin cell is bad.

    replace that and reset bios. set time,date and boot order to HDD0 1st.
    save ,exit ,bios.
    cold boot it now.
    PSU can be bad, as can all CAPS in this bad CAP year (era) PC.

Hi,

Please test your gateway using another monitor to see if the issue is consistent. Also, please remove an CDs or USB attachments from your computer.

I'm pretty sure the inverter board is bad. you have to replace it if you can or you can let someone else do it. you should find some on ebay for about $80 (not too bad compared to the cost of the monitor: over $200). but its up to you. But first, you should find out if you are still under warranty. good luck. please rate!!

SOURCE: gateway monitor, black screen with blinking power button

wjfarm48, Sure sounds like a power supply problem. How old is it? How many hours of use? Do you understand what a switch-mode-power-supply and an inverter supply is? If not, then here are your options. Check with Gateway to see if there is a swapout program. You box up and ship them your monitor+cash, and they return a REFURBISHED same model with new CCF tubes and inverter/SMPS. When you box up the monitor, follow this lead. "A 3 inch thick layer of breathable air shall be the only thing touching the lcd front panel" Next option is find some local TV/Monitor repair guy who can get parts and or replacement boards/CCFtubes from Gateway. Last but not least, is to repair yourself. Not Recomended.. But do a search on lcd monitor repair or Bad Capacitors In LCD Monitors or Repair of SMPS in LCD/FPD Monitors. Also check for videos on YouTUBE related to lcd monitor repair just for your own info. Here 's what you are dealing with. The light that makes your FPD bright white is generated by Cold Cathode Fluorescent Tubes (2) that require 600-1200vac at high frequency that is generated by an INVERTER which gets 12-24vdc from the SMPS. Almost the same technology is used in the new style screw-in curlie-que Compact Fluorescent light bulbs. Only they call the inverter a electronic ballast. Anyway, thats about all the info I have. Let me know how you make out in you quest to get your LCD up and running again. I'm louie12fix on fixya or lmistyrel@ aol.com BYE for now.

SOURCE: Gateway 19inch wide screen, lcd monitor stopped working randomly.

It could be a faulty power cord. Try plugging it in and moving the cord around in the areas where it takes the most movement. Do the same with the data cable to see if you get a response there. If your cables are fine, the problem is most likely hardware in the monitor - in that case you're better off replacing the monitor.

My moitor fpd1975w blinks blue power button and a white screen but does not turn on ?

The blinking power light is a good indication of a failed power supply board and the white screen backs that diagnosis up. Here is a link to information show what to look for and replace on the power supply board to get the monitor back up and running again. The repair involves replacing parts called capacitors on the power supply board and can be done in less than 20 minutes once you have the parts needed.

I have a gateway FPD1975W monitor with a Gateway GT5482E computer. The monitor does not display the computer output - the blue power light blinks off and on steadily and every so often the monitor says...

From your description you have a power supply problem, usually caused by defective capacitors, sometimes they will bulge at the top indicating an open condition. If you decide to repair check the inverter board that powers the back lights behind the screen, because they are also prone to bad caps.

How do I turn it on

Hello.

To power on the Gateway VX750, press the power button on the front. The power button has 3 sides with a "G" in the middle.

The LED indicates the power status of the monitor.
  • Not lit - The monitor is turned off or does not have power connected.
  • Blinks one time and then goes off - The LED blinks one time when the monitor's power cord is plugged into an AC outlet to indicate that power is detected.
  • Lit solid blue - The monitor is turned on and active.
  • Blinking blue - The monitor is in power saving mode. Before entering power saving mode, a message briefly appears.
Hope this helps.

My monitor does not turn on and the power button light keeps blinking ... <my Gateway monitor light blinks blue slowly but the screen is blank

This is usually a sign that there is no signal going to your monitor, check all your cables and then reboot.

No picture - blinking blue light. My daughter was

There are a few things you can check. First, try to see if the monitor cables are firmly connected on both sides (computer and monitor) no need to remove any cable for now just check the monitor cables (ends should be blue or white on both sides) Then check if you got an imput button on your screen (like all TV and some monitors now has) This input gives you the choice between a few possible connections and it may be on the wrong one. Just cycle trough the input modes and I think you will have your image back. If Still, you dont see anything, try a different monitor or try to connect your monitor on a different PC/laptop. In fact blinking blue could be there because the monitor is awaiting a signal on the input it's listening. At worst it could be because your video chip/card dont send a signal to your monitor, could happen, but imo it's probably not the case.
